Spawn a loomcycle evaluator
Use this when the operator wants an independent evaluation of work — either
the current Claude Code transcript or a specific loomcycle run — scored by a
loomcycle evaluator agent rather than by you directly.
Steps:
-
Identify what's being evaluated. Ask the operator (or infer) whether
they want to evaluate (a) the work in the current conversation, or (b) a
specific completed run. If (b), get the run_id.
-
Choose the evaluator agent. Ask which registered loomcycle agent should
act as evaluator (e.g. evaluator, judge). Do not guess a name — if none
is known, list options via the runs/agents the operator mentions, or ask.
-
Spawn the evaluator with mcp__loomcycle__spawn_run. Pass the material
to be judged as the prompt, wrapped as segments:
{
"agent": "<evaluator-agent>",
"segments": [
{ "role": "user", "content": [
{ "type": "trusted-text", "text": "Evaluate the following and return a score 0-1 with a one-line rationale:\n\n<material>" }
] }
]
}
Use the active user_id / user_bearer from /loomcycle:connect if set.
-
Report the evaluator's score + rationale back to the operator clearly.
-
Offer to record it. If the work corresponds to a real run_id, offer to
submit the score via /loomcycle:eval <run_id> <score>. loomcycle does not
auto-promote on scores — recording is the operator's call.
Keep the loop honest: you are orchestrating an independent judge, so don't
pre-bias the evaluator's prompt toward a verdict.
